Hi
Please replace code on path: root / templates/ot_keila/html/com_virtuemart/sublayouts/categories.php line from 79 to 83
replace
<div class="ot-cat-image">
<?php // if ($category->ids) {
echo $category->images[0]->displayMediaThumb("",false);
//} ?>
</div>
width
<div class="ot-cat-image">
<a href="<?php echo $caturl ?>" title="<?php echo $category->category_name ?>">
<?php // if ($category->ids) {
echo $category->images[0]->displayMediaThumb("",false);
//} ?>
</a>
</div>
there is a small note, Keila template is free, but when you use should be removed "Designed by OmegaTheme" footer.
We probably will not support you if do not have it on the site, because we have a policy for removing this, please refer to "Remove copyright or brand information"
